ADI ADUM7441ARQZ-RL7

磁耦合41000Vrms

Overview

The ADuM7440/ADuM7441/ADuM7442 are 4-channel digital isolators based on the Analog Devices, Inc., iCoupler® technology. Combining high speed CMOS and monolithic air core transformer technologies, these isolation components provide outstanding performance characteristics superior to the alternatives, such as optocoupler devices and other integrated couplers.

The ADuM7440/ADuM7441/ADuM7442 isolators provide four independent isolation channels in a variety of channel configurations and two data rates (see the Ordering Guide) up to 25 Mbps. All models operate with the supply voltage on either side ranging from 3.0 V to 5.5 V, providing compatibility with lower voltage systems as well as enabling voltage translation functionality across the isolation barrier. All products also have an output default high logic state in the absence of the input power.
